Project overview
To improve mobility on I-5 through Seattle, we will move barrier on a 1,500-foot section to create three through lanes near Seneca Street, add ramp meters for the Dearborn/I-90 and Cherry Street on-ramps and extend the Active Traffic and Demand Management system north to SR 520.
What to expect
Plan for weeknight overnight lane closures from 9 p.m. to 5 a.m. that will affect access to and from downtown Seattle. All traffic may shift to the collector/distributor and ramps to or from northbound I-5 may be closed.
Each of these nights the express lanes will remain open northbound, but the first express lanes exit is NE 42nd Street in the University District. People going to downtown Seattle should use the Edgar Martinez Dr. exit or take eastbound I-90 to Rainier Avenue.
Specific information is available on our real-time traffic map.
Work between Yesler Way and SR 520 will add a short section of a third lane between Seneca Street and the Washington State Convention Center, ramp meters at the Dearborn/I-90 and Cherry Street on-ramps and extend the Active Traffic and Demand Management system.
